unnecessary #PersPron is removed before its person grammateme is propagated to a node translated from Czech reflexive pronoun

In Czech, the antecedent of the reflexive pronoun is correctly found.
However, in the transfer to English the generated personal pronoun is removed, the coreference link as well, so there is no antecedent to replace the 'inher' value of the person grammateme.

There are two possible solutions:

1. propagate the grammateme values when removing the #PersPron during the transfer (probably cs->en only solution)
2. replace the 'inher' values of a person grammateme just after coreference resolution in the source language - in the same way, gender and number is propagated and disambiguated using Coref::DisambiguateGrammatemes
